Endothelial function can be assessed noninvasively by imaging the brachial artery with ultrasound before and during reactive hyperemia. However, the standard ultrasound equipment typically used for this purpose is limited by size and expense of the machinery. In this study, we compared the ability of a portable ultrasound device to standard ultrasound equipment to visualize the brachial artery for purposes of assessing peripheral vascular endothelial function. The portable device provided comparable imaging of the brachial artery at rest and during hyperemia to that of standard ultrasound technology. These findings support the feasibility of noninvasive evaluation of peripheral endothelial function in the ambulatory setting.
